Running GUI and APP parallel?

I’m wondering, if deCONZ GUI and APP can run parallel.

If I use the deconz.service the is no GUI available and on the other hand using deconz-gui.service there is no APP (no listener on port 80) available.

Both services are identical exept the option “-platform minimal”.

Can you check if it’s on 8080 instead of 80?

I am running gui and an able to use the app too.
